Study of the altarpiece of the Madonna and Child Enthroned with SS. Francis and Blaise and the Donor Luigi Gozzi by Titian, 1520, which the Ragusan merchant Lujo Gucetic commissioned for S. Francesco ad Alto in Ancona (now in the Pinacoteca comunale); cites documentary evidence establishing that Gozzi also commissioned the choir chapel and the new high altar, as well as documents dated 1652 referring to the removal of two figures from the painting; reaffirms the identification of the bishop saint as S. Blaise; and reexamines the view of the basin of S. Marco (Venice) in the background. ;
